i have what i think is the same system you are referring to. my system is totally manual with toggle switches on the dash for up and down for each of the 4 corners. it works great, but i did have to replace a few of the solenoids.
i do not have a tag axle and the solenoids are 6 under the front drivers side bumper, easily seen and accessed from just laying on the ground. the other 6 are on the firewall towards the front of the passenger side engine compartment.
i do have some sketches i will find on what valve is what. the travel valves are for the front on the front axle in the middle of the coach. the rear one is behind the tires on the drivers side on the outside of the frame.
michael is an expert on how to adjust them.
compared to the automatic hwh leveling systems, ours is very easy to troubleshoot and fix. i would love to have the automatic one, but i am very happy with mine as well. takes me just a few minutes to level when i stop.
